Abstract
Many of studies aiming at grasp of the actual condition of heat-island phenomenon in recent years are the moving observations which need time correction and the fixed point observation with few measuring points. In consideration of these situations, the long-term fixed point observation which can acquire data which is high resolvable in time and spatially is performed in this study. In previous study, the measuring method of the long-term fixed point observation of the temperature and humidity observed at about 160 points in Kumamoto city was explained in full detail. While the temperature and the humidity distribution obtained from the measurement result were shown, the characteristic of temperature change of each measuring point was clarified by using the principal component analysis about temperature change etc. In this study, the feature of the climate of Kumamoto city is solved based on the observation result of summer heat day and chill day. And, in Kumamoto-city where temperature and humidity is high, the influence the strength of a wind has on temperature distribution is considered. Furthermore, the feature of moving observation of the temperature distribution and the long-term fixed point observation adopted by this study is shown. Based on each measurement result, the actual condition of the heat-island phenomenon in Kumamoto city is solved.
